'RAIL-ANCHOR.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application led May 19, 1916. Serial No. 98,529.

To all 'whom it may concern:

Be it known that I, HoRATIo G. GILLMOR, a citizen of the United States, residing at lVashington, in theDistrict of Columbia, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates Vto a rail anchor, anticreeper or rail stay 'and the principal object of the invention is to provide a device which may be used in connection with and attached to a tie plate, whichvwill be simple in construction, light= in weight, inexpensive to manufacture and which will efl'ectually hold the rail, will not be loosened by vibration, changes of temperature or other causes that tend to impair the grip or holding power which is essential to the efficiency of a device of this character.

A further and specific object of the invention is to provide a novel form of rail anchor utilizing spring pressure for effecting and maintaining a grip of the device upon the rail.

A further object is to provide a device which is wedged against both the head and the base flange of the rail in such manner that the holding power of the device under all conditions will be good.

A further object of the invention is to provide a device the grip of which on the rail will not be affected by retrograde movement of the rail that is, movement of the rail in a direction the reverse of the normal creep.

The invention is illustrated in a preferred embodiment, in the accompanying drawing. wherein- Figure l illustrates, in elevation, theV structure constructed in accordance with the invention, applied to a rail which is shown in section. Fig. 2 is a side elevation of the device and the tie plate showing a portion of the rail and the tie. Fig. 3 is a section of the parts at* the plane Vindicated by the line X X in Fig. 2, showing the device in one of the positions assumed while the device is being applied. Fig. lis a plan view of the parts shown in Figs. l and 2.

Like characters of reference designate like parts in the several igures of the drawing.

In the drawing A represents a railway rail of the usual construction having a head B and a base flange C, resting upon a tie plate D which may be any one of the several kinds of tie plates ordinarily use d in railway construction, having spiking apertures such as E some of which are traversed by spikes F which are driven into the tie Gr upon which the tie plate D rests supporting the rail thereon. Engaging a spiking aperture E at one side of the rail, is the rail en gaging and gripping part H the portion I of which engages the spiking aperture E in the tie Aplate D. The part H is constructed with a recess K arranged to receive a spring L, here shown helical in form and guided by the portion M o-f the part H. The part H is provided with a surface N which engages the under surface of the head B of the rail and a stiening rib O with an enlarged portion P is provided for strengthening the part H. To providey properly for the spring aperture or recess K the part H is constructed with a bossed portion R within which the recess K is formed. I v

The device is placed in position by inserting the portion I of the part H in the spiking aperture E of the tie plate D with the spring L in place in the recess K and moving the part H with the portion I engaging the aperture E to the position shown in Fig. 3 when the surface N will begin to engage the under surface of the head B of the rail A. In this position the spring L is exerting a pressure upon the part H in a direction normal to the upper surface of the base flange C of the rail and one component of the pressure exerted by the spring is tending to push the part H upward and the other component of the spring pressure is tending to push the part H out from the rail. The upward pressure is resisted by the engagement of the surface N of the part H with the under surface of the rail head B and the pressure tending to push the part H out from the rail is resisted by the engagement of the portion I of the part H with the spiking aperture E in the tie plate D. rIhe tie plate D may be formed with a projecting portion Q to engage the edge of the rail base C at the side of the rail opposite to the part H or the spikes F may be employed to hold the tie plate in position and resist the lateral pressure exerted upon the tie plate D by the portion I of the part H. lFrom the position of the part H shown in Fig. 3 it may be driven or forced with a suitable wrench to the final operative position illustrated in Figs. l, 2 and 4. The spring .will7 by this forcing of the part I-I into place, be compressed and in the final operative position of the device the rail base (l and the under side of the rail head B will be strongly gripped by the part H and the spring L and the spring L in its compressed or' iiattened condition will exert a strong pressure upon the upper surface ofthe iail base flange C and upon the' part H. The engagement of the portion I of the part H with the aperture E in the tie plate D will hold the part H against lateral displacement and the part H and the spring L gripping the rail' A firmly hold the rail against longitudinal or creeping movement by the engagement of the portion I of the part H with the tie plate D.

As will be apparent from the above description and drawing the anchor is adapted to prevent the rail from moving l`ongitudinally in either direction so that tendency of the rail' to move in a directionA the reverse of that in which the general' tendency of the rail is to creep will not aii'ect the gripofthe device upon. the rail. .Moreover the anchor is reversible and may be applied to either side of t'he rail as may be dictated by local. conditions.

Although the device is herein shown and described in its preferred embodiment, it will be understood that changes and modiiications may be made without departing from the spirit of the' invention and all such changes and mod-iiications are contemplated as fall within the scope of the claims. l
